1Normally-closed contact K
1Be serially connected in the current supply circuit of magnetic valve 7.
A kind of embodiment circuit structure of described time-delay adjusted circuit 11 also as shown in Figure 3, it comprises IC chip CD4060 (ten level Four binary dividers) and triode VT, diode VD, relay J
1, J
2
Referring to Fig. 1, the new a kind of practical application of this practicality is, source of the gas (for example cylinder for liquefied gas) 9 joins through an end of a sebific duct and a three-way connection 8, this three-way connection 8 two ports in addition is connected with the end of magnetic valve 7 with manual air valve 6 respectively, and the other end of described valve 7,6 is connected with other two ports of three-way connection 5 respectively, the another port of this three-way connection 5 is connected with burner (gas range or water heater) 4 through sebific duct, the A of master controller 1, B termination civil power (220V) power supply 10, C, D termination magnetic valve 7, E, F, G termination human body induction module 3; Under the air feed state, because magnetic valve 7 (comprising hand-operated valve 6) is in closed condition, gas appliance can not be worked, and at this moment, even the changeover valve of gas appliance is forgotten closes and is in open mode, and combustion gas can not leaked yet.When needs were heated up water or cooked, as long as the button among Fig. 1 or Fig. 22 (being the AN among Fig. 3) is clicked, circuit was connected, and magnetic valve is opened, and gas-flow is to kitchen range.Press the effect of AN, come down to make electric current flow through relay J with the bidirectional triode thyristor SCR short circuit among Fig. 3 once
1Normally-closed contact K
1, it is electric that C and D binding post formation loop get magnetic valve, and SCR has also obtained trigger current and conducting simultaneously.After unclamping AN, because of C
1Be filled with electric charge, so when the alternating current zero passage, C
1Discharge is kept SCR and is continued conducting, and this is equivalent to the self-locking conducting.IC integrated circuit CD4060 comes down to 14 grades of binary dividers, and inside comprises oscillator and frequency divider, and frequency of oscillation has also just determined the length of its delay time by external RC decision.In magnetic valve energising work constantly, 12 pin presets of IC, internal oscillator opens and shakes, behind 14 grades of frequency divisions, by the high electricity of 3 pin output frequently, control controllable silicon BCR conducting, relay J
1Action, normally-closed contact K
1Disconnect magnetic valve dead electricity and turn-offing.If someone be interrupted when selected scope activity, human body induction module 3 can be experienced the energy that human body discharges, through inside modules circuit amplifying signal, relatively differentiate with handle after, II pin output high level, make the rapid conducting of triode VT through the F binding post, allow relay J
2Normally opened contact K
2Closure, CD4060 resets, the circuit reclocking ...As long as have the people intermittently movable thereby reached, magnetic valve can be in all the time to be opened and guarantees the state of air feed.
In addition, 220 volts of alternating currents provide 12 volts of stable direct currents through AC/DC power conversion module 12 to time-delay adjusted circuit 11, make it work.Human body induction module 3 has also obtained 12 volts of stable direct currents through binding post E, G, makes it to experience the energy of human body reliably and sends signal.
The utility model mainly is the energy that is produced when having utilized physical activity, make human body induction module send signal to delay circuit off and on, cause delay circuit in time to reset and reclocking constantly, thereby allow magnetic valve when having the people movable, can be in open mode; When the people leave effective scope of activities, through the selected time after, can cut off the power supply automatically, make closed electromagnetic valve, cut off source of the gas, thereby realize the purpose of this utility model.
As known from the above, the utility model is a kind of gaseous fuel self-control safety device, and following characteristics are arranged:
(1) operation is very simple, need only when needs are used gas button (AN) 2 be clicked, and promptly enters duty.
(2) after unmanned activity or personnel go out, can guarantee to close gas automatically, prevent pipeline gas leakage and eliminated owing to forget the accident potential that Guan Huoer stays.
Power consumption very little (depending primarily on magnetic valve power) when (3) working, not power consumption after automatically shutting down.This is because 12 power consumption streams of AC/DC conversion module are too little, has no progeny as long as magnetic valve closes, and SCR just can not keep conducting and be turned off, and has promptly realized the function that cuts off self-lock.
(4) meeting by chance under the situation of power failure, can use the manual auxiliary valve in parallel, guaranteeing gas just commonly used with magnetic valve.
(5) be adapted to all families, no matter be piped gas or liquefied petroleum gas.
(6) simple in structure, make easily.Volume is little, price is low.
